Technical Abstract

An electronic device is provided. The electronic device includes a substrate, a plurality of signal lines and a plurality of units. The signal lines are disposed on the substrate. The units are disposed on the substrate. At least one of the units includes a first main pad, a first redundant pad, and an electronic component including a first electrode. In addition, one of the signal lines is electrically connected to the first electrode of the electronic component, the first main pad and the first redundant pad.

Patent Claims
15 claims

Legal claims defining the scope of protection, as filed with the USPTO.

2

2. The electronic device as claimed in claim 1, wherein the first main pad and the first redundant pad are disposed on different horizontal planes.

3

3. The electronic device as claimed in claim 2, wherein the first main pad at least partially overlaps the first redundant pad.

4

4. The electronic device as claimed in claim 1, wherein the at least one of the plurality of units comprises a second main pad, and the electronic component further comprises a second electrode electrically connected to the second main pad and another one of the plurality of signal lines.

5

5. The electronic device as claimed in claim 1, wherein the electronic component further comprises an n-electrode and a p-electrode, the one of the plurality of signal lines provides a signal for the n-electrode, and another one of the plurality of signal lines provides a signal for the p-electrode.

6

6. The electronic device as claimed in claim 1, wherein the electronic component further comprises three n-electrodes and a p-electrode, the one of the plurality of signal lines provides a signal for one of the three n-electrodes, and another one of the plurality of signal lines provides a signal for another one the of the three n-electrodes.

7

7. The electronic device as claimed in claim 1, wherein the electronic component further comprises three p-electrodes and an n-electrode, the one of the plurality of signal lines provides a signal for one of the three p-electrodes, and another one of the plurality of signal lines provides a signal for another one the of the three p-electrodes.

8

8. The electronic device as claimed in claim 1, wherein a minimum distance between the first main pad and the first redundant pads is less than half of a minimum distance between the first main pad in one of the plurality of units and the first main pad in another one of the plurality of units.

9

9. The electronic device as claimed in claim 1, wherein a surface of the wavelength conversion layer facing toward the first main pad and the first redundant pad is a concave.

10

10. The electronic device as claimed in claim 1, wherein an area of the first main pad is different from an area of the first redundant pad.

11

11. The electronic device as claimed in claim 1, wherein at least one of the plurality of units further comprises a light-shielding layer disposed adjacent to the wavelength conversion layer; and the first main pad at least partially overlaps the light-shielding layer.

13

13. The manufacturing method of electronic device as claimed in claim 12, wherein disconnecting the electrical connection between the one of the plurality of signal lines and the first electronic component is performed by a laser cutting process.

14

14. The manufacturing method of electronic device as claimed in claim 13, the first electronic component further comprising a plurality of electrodes, wherein an electrical connection between one of the plurality of electrodes and the one of the plurality of signal lines is cut by the laser cutting process.

15

15. The manufacturing method of electronic device as claimed in claim 13, wherein the one of the plurality of signal lines comprises a main line and a branch line, the branch line is connected between the main line and the first main pad, and the branch line is cut by the laser cutting process.

16

16. The manufacturing method of electronic device as claimed in claim 12, wherein disconnecting the electrical connection between the one of the plurality of signal lines and the first electronic component is performed by removing the first electronic component.

17

17. The manufacturing method of electronic device as claimed in claim 12, wherein the first electronic component is a dysfunctional electronic component.
